### Unit 2: Lesson 6

Lesson 10: Meet slope

# Intro to slope

Sal shows how to find the slope of a line.

## Want to join the conversation?

• Without doing any calculations how do you know that one slope has a higher slope than another line?
• You can know if one slope has a higher slope without calculations because the higher the slope the steeper the line. Great question!
• I don't get slope at all; can somebody explain it to me?
• Slope means inclination of a line. For example you draw a graph and draw two lines and find that slope ?try it and tell!
• How do you find slope of a straight horizontal line? my brother said it would be one, but im not sure... Thanks in advance!
• Why can't it be 'increase in horizontal/ increase in vertical' or 'run over rise'?
• It kinda makes no sense as we are measuring the amount of steepness i.e higher the number --> steeper the slope. In your question it is the opposite
• what if the line is straight??
• If a line is straight horizontally then the slope would be 0 but if the line is straight vertically the slope would be undefined
• Without doing any calculations how do you know that one slope has a higher slope than another line?
• You just imagine both of them in on place
or look which one has greater angle from same x line
• Slope is also y2 - y1 / x2 - x1, right?
